Detailed Description

Represents a JSON channel to a subject on the Liberator.

A Channel provides a bi-directional communication channel between a StreamLink application and a DataSource adapter. Using a Channel in both DataSource and StreamLink provides a simplified method of communication between the two components and can allow you just to use the Caplin platform as a bi-directional messaging pipe.
